終於，我們英雄的真實身分受保護了！🥷

它也重新宣告了 `id: int`。這麼做是與 API 用戶端訂立一個「契約」，讓他們可以確定 `id` 一定存在而且是 `int`（不會是 `None`）。

/// tip | 提示

讓回傳模型保證某個值一定存在、而且一定是 `int`（不是 `None`），對 API 用戶端非常有幫助。他們在有這個確信下可以寫出更簡單的程式碼。

此外，透過「自動產生的客戶端」也會有更簡潔的介面，讓要使用你 API 的開發者能有更好的開發體驗。😎

`HeroPublic` 中的欄位與 `HeroBase` 相同，僅 `id` 宣告為 `int`（非 `None`）：

* `id`
* `name`
* `age`
